How much does an AI answering service really cost?

An AI answering service costs whatever its pricing model makes it cost, and the headline rate is rarely the whole invoice. BotsDontSleep bills $0.60 CAD per answered minute, 24/7, with $0 setup, no monthly minimum and no contract, so a business taking 300 answered minutes a month pays about $180 and a slow month bills less on its own. Four things move the real number: the pricing model, the billing increment, the minimum, and what the vendor decides is billable.

What does an AI answering service cost per month?

Take your answered calls, multiply by your average call length, multiply by the rate. At $0.60 CAD a minute that arithmetic is short enough to do in your head, and it is worth doing with your own figures rather than a vendor's example.

Three real shapes of business, using two minutes as a planning figure where the business does not know its own average:

• A one-van plumber. About 45 calls a month, averaging 90 seconds — quotes, callbacks, and a lot of wrong numbers. That is roughly 68 answered minutes, or about $41 a month.
• An eight-bay auto shop. About 220 calls a month at 2.5 minutes each, because status calls run long. That is 550 minutes, or $330 a month.
• A three-chair dental clinic. About 600 calls a month at 2 minutes, heavy on booking and rescheduling. That is 1,200 minutes, or $720 a month.

None of those numbers has a floor under it. The plumber's quiet December costs less than his June without anyone changing a plan, because there is no minimum to fall through.

How do AI answering services charge?

Four models are in common use, and they produce very different invoices from the same call log.

Per answered minute. You pay for talk time only. Short calls are cheap, long calls are not, and a month with no calls costs nothing. This is what BotsDontSleep does, billed by the second.

Per call. A flat price regardless of length, usually inside a monthly bundle with an overage rate. Long calls are cheap and wrong numbers are expensive, because a nine-second hang-up bills the same as a nine-minute intake.

Monthly plan with included minutes. A fixed fee buys a block of minutes, with an overage rate above it. Predictable if your volume is flat, punishing at both ends — unused minutes expire and overage minutes cost more than the ones inside the plan.

Per seat or per line. Priced like software, by how many people or numbers are attached rather than by calls. It stops tracking usage entirely, which helps if you take a great many calls and hurts if you do not.

What is missing from the headline rate?

Six things, none of which usually appear beside the number in the pricing hero.

• Setup and onboarding. Often several hundred dollars, charged once, and frequently quoted only after a sales call. BotsDontSleep charges $0, including call-flow mapping, tuning, and calendar and CRM integration.
• The monthly minimum. A 200-minute floor means a slow month costs the same as an average one.
• Integration fees. Some providers price a calendar or CRM connection as an add-on per month.
• Language surcharges. Bilingual handling is sometimes a separate line item, sometimes a separate phone number. All 90+ languages are included here at the same rate, including mid-sentence code-switching.
• Hold, transfer, and wrap time. Ask specifically whether the clock runs while a caller waits or while an agent writes up notes after the call ends.
• The notice period. Not a fee, but it behaves like one. An annual term with 60 days' notice is up to fourteen months of committed spend on the day you sign.

Does per-second billing actually change the invoice?

Yes, and by more than it sounds. The gap only shows up on short calls, which is exactly where most business phone traffic lives.

A twenty-second wrong number costs about 20 cents at $0.60 a minute billed by the second. Rounded up to a full minute it costs 60 cents — three times as much for the same twenty seconds. Scale that to a normal week: fourteen robocalls and misdials at about thirty seconds each total roughly seven minutes, or $4.20. Billed in rounded-up minutes those same fourteen calls total fourteen minutes, or $8.40. The rate did not change. The invoice doubled.

Ask any provider two questions: what is the billing increment, and is there a minimum billable duration per call. A one-minute minimum with per-second billing after it is a different product from true per-second billing, and the difference lands entirely on your shortest calls.

Is per-call pricing cheaper than per-minute?

It depends on how long your calls run, and the crossover point is easy to find once you convert a per-call plan into a per-call price.

Smith.ai, a live-staffed service, publishes three plans: $300 USD a month for 30 calls, $810 for 90, and $2,100 for 300, with overage at $11.50, $10.50, and $8.50 per call respectively, no setup fee and month-to-month billing (smith.ai/pricing, as published 15 August 2026 — check their site for current figures). Divide the plan by its call allowance and the included calls work out to $10.00, $9.00, and $7.00 each.

Now price the same 300 calls per minute. At an average of two minutes that is 600 answered minutes, or $360 CAD. At four minutes it is 1,200 minutes, or $720. At ten minutes — genuinely long intake calls — it is 3,000 minutes, or $1,800, and the per-call plan finally starts to look competitive. Those figures are quoted in different currencies and are not converted; compare them against your own volume rather than against each other.

The general rule holds without the arithmetic. Per-call pricing favours businesses with long calls and clean call logs. Per-minute favours short calls and forgives junk traffic. Count your wrong numbers before you choose.

How do the pricing models compare?

Cost figures for other providers are as published on the dates named in this post and in the currency their source quotes; check each provider's own site before deciding anything.

How do you work out your own monthly cost before signing?

Five steps, in this order. All of them use your numbers, not a vendor's.

1. Pull last month's call log. Your phone provider has it. You want total inbound calls and, if it is available, duration per call — not an estimate from memory.
2. Separate the junk. Count the robocalls, wrong numbers, and hang-ups under fifteen seconds. On most small-business lines this is between a fifth and a third of all calls, and it is the number that decides whether per-call pricing will hurt you.
3. Find your average answered length. Total duration divided by answered calls. If your log does not carry duration, use two minutes as a planning figure and correct it after your first month of real transcripts.
4. Price every quote against that same log. Multiply your minutes by each per-minute rate, your calls by each per-call rate, then add setup fees, minimums, and any integration or language line items. Compare monthly totals, never rates.
5. Decide what a booked job is worth. A two-minute booking call costs about $1.20 at $0.60 a minute. Set that beside the value of one job you would otherwise have lost to voicemail, and the arithmetic usually stops being about the rate at all.

When is $0.60 a minute the wrong deal for you?

Three cases, and we would rather name them than have you find them on an invoice.

When your calls are genuinely long. Per-minute pricing rewards short calls. If your average intake runs fifteen or twenty minutes — a family law consultation, a detailed insurance intake — the per-minute model works against you, and a flat monthly plan may cost less for the same work. Do the arithmetic on your real average before switching to us.

When your volume is very high and very steady. A business taking 5,000 answered minutes a month at a predictable rate is exactly who a bundled plan is priced for. At that volume, ask us for a quote rather than assuming the published rate is the best available, and compare it honestly against a plan.

When the phone is not the problem. If fewer than about twenty calls a month reach you and you answer nearly all of them, no service of any kind will find you money. And if your enquiries arrive by web chat, form, or email, this is the wrong product — BotsDontSleep is a voice product, and it does not run your web chat.

A human receptionist is a separate calculation again. Ontario's general minimum wage is $17.60 an hour, rising to $17.95 on 1 October 2026, and front-desk roles are commonly posted well above it; that comparison has its own arithmetic and its own trade-offs.

The rate is the easiest part of this decision to check and the least likely to be what costs you money. The minimum, the increment, and the notice period are where the invoice actually comes from.
